Official ZynthianOS SD-Images
You can download the last official ZynthianOS SD-Image, based on Raspberry Pi OS, from here:

Last Stable ZynthianOS (MD5-sum)

Unzipping
The file you download is a zip file that must be unzipped to get a .img file that can be 'burnt' to the micro-SD card used by the zynthian device (Raspberry Pi). This process differs depending on the operating system you normally use: windows, mac or linux.

Preparing the SD-card
Latest SD-card image weight around 8 GB compressed and around 14 GB unzipped. It includes all the software you need for your zynthian, properly configured for working out-the-box with the latest official kits. Completely ready to use. Plug and play!

After downloading and unzipping the SD-image, you have to write it to a suitable SD-card. You need a good-quality SD-card with a minimum size of 16GB. You can use a bigger one if you like.

You can use Etcher, free software that works on Mac, Windows and Linux, to write the image into the SD-card. You can do it from the terminal too, using dd or pv cli tools. There is a really good manual for this at this link.

Configuration instructions
Latest SD-image auto-detects latest official kits V3, V4 & V5. If you are using a different/custom hardware, your first step after booting should be accessing the webconf and configuring your hardware.


 * For accessing the webconf tool, see here
 * Once logged-in, go to Hardware -> Kit and select your kit version or "Custom". Click on save button.
 * Then, if you have a custom hardware configuration, configure each device: Audio, Display, Wiring. Use "Dummies" if you don't use any encoder/switch. Don't forget to save your configuration after each step.
 * When everything is configured, you can reboot Zynthian using the System -> Reboot menu item
